The invention relates to a power battery health degree evaluation method, a power battery health degree evaluation device, a storage medium and a server. The health degree evaluation method of the power battery comprises the steps of collecting time data, vehicle speed data, mileage data and electric quantity data generated by change of each unit SOC in a predetermined state-of-charge interval when a predetermined vehicle runs under a predetermined condition; based on the time data, the vehicle speed data, the mileage data and the electric quantity data generated by the change of each unit SOC in the predetermined state-of-charge interval, obtaining average time length data, average mileage data and average electricity consumption data corresponding to different vehicle speed sections generated when the predetermined vehicle runs under the change of the vehicle speed; and based on the average duration data, the average mileage data and the average power consumption data corresponding to different vehicle speed sections generated by the change of each unit SOC in a predetermined state-of-charge interval when a predetermined vehicle runs under a predetermined condition, the battery health degree of the power battery is evaluated, and data support is provided for a user to use the vehicle.

    本公开是关于一种动力电池的健康度评估方法、动力电池的健康度评估装置、存储介质及服务器。该动力电池的健康度评估方法包括采集预定车辆在预定条件下行驶时预定荷电状态区间内每单位SOC变化产生的时间数据、车速数据、里程数据及电量数据;基于预定荷电状态区间内每单位SOC变化产生的时间数据、车速数据、里程数据及电量数据,得到预定车辆在车速变化下行驶时产生的不同车速段对应的平均时长数据、平均里程数据及平均用电量数据;基于预定车辆在预定条件下行驶时预定荷电状态区间内每单位SOC变化产生的不同车速段对应的平均时长数据、平均里程数据及平均用电量数据,评估动力电池的电池健康度,为用户用车提供数据支持。
